High concern

Polyglyceryl-2 sesquiisostearate is a non-ionic polyglycerol fatty acid ester used primarily as an emulsifier/surfactant, especially for oil-in-water or water-in-oil systems. It helps blend oil and water phases, improve spreadability, and support a smooth, elegant skin feel. It is generally considered a mild, formulation-supporting ingredient rather than a treatment active.
